Kinematics Question 787
Question: If $ a _{r} $ and $ a _{t} $ represent radial and tangential accelerations, the motion of a particle will be uniformly circular if[CPMT 2004]
Options:
A) $ a _{r}=0 $ and $ a _{t}=0 $
B)$ a _{r}=0 $ but $ a _{t}\ne 0 $
C) $ a _{r}\ne 0 $ but $ a _{t}=0 $
D) $ a _{r}\ne 0 $ and $ a _{t}\ne 0 $
Show Answer
Answer:
Correct Answer: C
Solution:
In uniform circular motion tangential acceleration remains zero but magnitude of radial acceleration remains constant.
